SILO-DOOR AND FASTENER.

Specification of Letters Patent.

Patented July 13, 1909.

Application filed January 20, 1909. Serial No. 473,302.

To all whom it may concern:

Be it known that I, KNUT KLEvnN, a citizen of the United States, residing at Mount Horeb, in the county of Dame and State of Wisconsin, have invented a new and useful Silo-Door and Fastener, of which the following is a specification.

This invention relates to silos and more particularly to improved means for locking the several door sections of the silo in closed position. v

The object of the invention is to provide a silo having a continuous door opening and provided with a plurality of removable door sections forming a closure for said opening, there being a transverse bar secured to the exterior face of each door section and coacting with ivoted members on the. door frame for locizing the door sections in closed position.

A further object is to provide means for -clamping the transverse bars of the door sections in engagement with the pivoted members after the latter have been swung downwardly at the rear of said transverse bars.

A still further objcct'of the invention is generally to improve this class of devices so as to increase their utility, durability and efficiency.

Further objects and advantages will appear in the following description, it being understood that various changes in form, proportions and minor details of construction may be resorted to within the scope of the appended claims.

In the accompanying drawings forming a part of this specification: Figure l is a plan view of a portion of a silo constructed in accordance with my invention. Fig. 2 is a vertical sectional view of the same. Fig. 3 is a transverse sectional view taken on the line 33 of Fig. 1. Fig. 4 is a detail per spective view of one of the fastening devices detached.

Similar numerals of reference indicate corresponding parts in all of the figures of the drawings.

The improved silo' forming the subject matter of the present invention includes a substantially cylindrical body portion 5, preferably formed of tongue andgroove staves, and having its exterior walls reinforced and strengthened by the provision of a plurality of circumferential hoops 6. Two

or more of the staves on one side of the silo are removed to produce a door-opening, preferably extending the entire height of the silo, and in which is seated a door frame 7 --verse strips connected by spaced vertically disposed cleats 12, the' latter being ri idly combined with the body of the door by olts or similar fastening devices 13. The outer longitudinal edges of the cleats are preferably inclined or beveled in opposite directions from a central flat portion 14, and bearmg against the flat portions of the cleats 12 of each door is a transverse. bar 15, the opposite ends of which are bent inwardly to produce angularly disposed fingers 16. I

Pivotally mounted at 17 on the longltudlnal bars of the door frame at the opposite ends of the transverse bars 15 are locking members or latches 18 adapted to be swung downwardly to operative position at the rear of, and in engagement with the fingers 1 of the bars 15 so as to prevent the door sectlons from dropping downward within the silo.

As a means for positively clamping the transverse bars 15 in cngagementwith the adjacent locking members 18, there-are provided transverse bolts 19 which extend through the body of the door and the ad acent longitudinal cleats 12 with their ternunals 20 projecting through the flat bearing surfaces 14 for engagement with suitable clamping nuts 21, the latter being provided with terminal finger pieces 22 so that the nuts may be rotated, thereby to bear against the exterior face of the bars 15 and thus force the finge s 16 of said bars laterally against the pivoted locking members 18. It will here be noted that the downward swinging movement of the locking members 18 is limited by engagement with suitable stop or other edges 10 of I pins or studs 23 carried by the longitudinal ars of the door frame, whereby when the locking members are moved to operative position, the same will'be supported in horizontal alinement with the adjacent transverse bars 15.- It will also be noted that by spacing the transverse bars 15 from the ex terior face ofthe door-sections, said trans verse bars form in effect the rounds of a ladder so that an attendant may readily ascend or descend the silo. Thus it will be seen that by rotating theiinger pieces 22 in one direction, the terminals 16 of the locking bars may be disengaged from the pivoted members 18 so as to permit the'latter to be swung laterally to inoperative position, and inwhioh position the door sections may be readily removed.

In order to replace the door sections it is merely necessary to position the same within the silo with the upper and lower edges thereof bearing against the shoulders 1160f the adjacent transverse.bars 8 and with the opposite longitudinal edges of the door sections bearing against the inner face of the door frame 7 after which the pivoted locking members 18 are swung downwardly at the rear of the angular extensions 16 of the transverse bars and the finger pieces 22 of the clamping nuts adjusted to securely clamp the several parts together, 'in 'the manner before described.

Having thus described is claimed is: r

l. A silo including a body portion having a door opening, a plurality of removable door sections forming a closure for said opening, a transverse bar secured to the exterior face of each door section, andlocking members pivotally mounted on the body portion and movable laterally into engagement with the adjacent transverse bars.

2. A silo including a body portion having the invention what a door opening, a plurality of removable door sections forming a closure for said openmg, a transverse bar secured to each section and provided with angular extensions, and
